Answer:
1. Predator-Prey
2. Mutualism
Explanation:
The cow consumes the grass. The cow is the predator and the grass is the prey.
The clownfish gets protection from the anemone and in return, the urine of the fish benefits the anemone. Both organisms get the benefit so it’s mutualism.
why animals need to move quickly
Answer:
Animals move for a variety of reasons, such as to find food, a mate, a suitable microhabitat, or to escape predators. For many animals, the ability to move is essential for survival and, as a result, natural selection has shaped the locomotion methods and mechanisms used by moving organisms.

A coin is flipped 150 times. The results of the experiment are shown in the following table:
Heads Tails
84 66
Which of the following statements best describes the experimental probability of getting heads?
It is equal to the theoretical probability.
It is 6% lower than the theoretical probability.
It is 6% higher than the theoretical probability.
The experimental probability cannot be concluded from the data in the table.
Answer:
it is 6% higher than the theoretical probability.
Explanation:
we start with out experimental.
84 times heads out of 150.
84/150 = 56.
=56%
now for theoretical.
since there are 2 sides, there are 2 chances of randomly getting heads.
1/2 = 50%
56% > 50%
therefore your answer is that it is 6% higher. hope my explanation helps!

Suggest why redox indicators highlight aerobic respiration.
Answer:
Cellular respiration involves many reactions in which electrons are passed from one molecule to another. Reactions involving electron transfers are known as oxidation-reduction reactions (or redox reactions).
How can noise pollution harm wildlife?
A. It confuses organisms that rely on cycles of day and night.
B. It removes essentials nutrients from organisms’ habitats.
C. It prevents animals from catching prey or escaping predators.
D. It increases the body temperatures of organisms to harmful levels.
C. It prevents animals from catching prey or escaping predators is the correct option.
What is noise pollution?Noise pollution also understood as environmental noise or sound pollution, exists as the propagation of noise with ranging consequences on the activity of human or animal life, most of them detrimental to a degree. The source of outdoor noise worldwide exists mainly caused by machines, transport, and propagation techniques.
Noise pollution also understood as environmental noise exists as the propagation of potentially “damaging” sounds via the environment. The impacts of noise pollution tend to be seen as a nuisance rather than an environmental concern for decades.
Noise pollution harm wildlife by preventing animals from catching prey or escaping predators.Due to noise pollution the prey organisms do not come out from their habitat. It becomes difficult for the predator to catch their prey if they do not comes out. Also prey organisms gets frightened and fails to escape from their predators.

Which features are critical for surival of bacteria cell?
Answer:
A host
Explanation:
A 20.0 gram sample of a certain radioisotope decays over a
period of 19.2 hours. After that time, only 2.50 g of the isotope
remains. Calculate the half-life.
quantity of the substance remaining = initial quantity of the substance * (.5)^(time elapsed/half life of the substance)
2.50 = 20 * (.5)^(19.2/x)
The half-life period of the given sample of the radioisotope is equal to 6.41 hours.
What is the half-life period?The half-life of a radioactive substance is defined as the time that is required to reduce the original quantity of a radioactive element to half after decay.
Half-life of a radioactive element is the characteristic of the element and does not depend upon the initial amount of the radioactive substance.
Given, the original amount of the radioisotope, N₀ = 20.0 g
The remaining amount of the radioisotope, N = 2.50 g
The time for which decay occurs, t = 19.2 hours
Consider that k is the rate constant of the decay of radioisotope,
[tex]k =\frac{2.303}{t} \times log \frac{N_0}{N}[/tex]
[tex]k =\frac{2.303}{19.2} log \frac{20}{2.50}[/tex]
k = 0.108 hr⁻¹
The half-life time of radioisotope can be calculated from the below mentioned formula:
[tex]t_{\frac{1}{2}} =\frac{0.693}{k}[/tex]
[tex]t_{\frac{1}{2}} =\frac{0.693}{0.108}[/tex]
[tex]t_{\frac{1}{2}} =6.41 hrs[/tex]
Therefore, the half-life period of the given sample of the radioisotope will be to 6.41 hours.

Which description accurately describes the cell membrane?
a. a single permeable layer of phospholipids that have hydrophobic heads and hydrophilic tails
b. a semi-permeable double layer of phospholipids that have hydrophilic heads and hydrophobic tails
c. a single permeable layer of phospholipids that have hydrophilic heads and hydrophobic tails
d. a semi-permeable double layer of phospholipids that have hydrophobic heads and hydrophilic tails
e. a barrier of polypeptides that prevents molecules from entering or leaving the cell
Answer:
b. a semi-permeable double layer of phospholipids that have hydrophilic heads and hydrophobic tails
Explanation:
B is correct as the cell membrane is selectively semi-permeable. It is selectively semi-permeable because this quality allows it to control what can and can't enter the cell, and how it does so.
The cell membrane also has a phospholipid bi-layer comprised of a double layer of phospholipids which have hydrophilic head and hydrophobic tails. This is because the heads are made of phosphate and are polar and are therefore attracted to water (hydrophilic), while the tails are made of lipids (i.e. fats, oils) which do not mix with water and are therefore hydrophobic.
The properties of each phospholipid is also why they form the double layer structure, the hydrophilic heads naturally face outwards into the water and protect the hydrophobic tails on the inside.

This paramecium has a nucleus and is comprised of one cell. Which terms best describe this organism?
Answer: The term that best describes this organism is that it's a UNICELLULAR PROTISTA.
Explanation:
Unicellular organisms are that are made up of just one cell. They are also called single- celled organisms. Examples of unicellular organisms include: Amoeba, chlamydomonas and paramecium.
The paramecium is a protist which is SINGLE-CELLED and is made up of eucaryotic cells in which the cell structure is complex with a well-defined NUCLEUS.
The structure of this organism helps it to survive in its environment. It has cilia that helps it move food into its gullet.
The food vacuole circulate along a definite path in the cytoplasm. The anterior and posterior contractile vacuole, with radiating channels draining into them, helps to get rid of excess water from the body. The food vacuoles circulate along a definite path in the cytoplasm. The anterior and posterior contractile vacuole, with radiating channels draining into them, helps to get rid of excess water from the body.
The NUCLEUS is used by the organism for sexual reproduction. This occurs in a process known as conjugation whereby the whole organism pair with another similar whole organism and exchange their nuclei.

How does the body structure evolve for animals as they transmit between the two environments?
Answer:
Biologists believe that new species evolve from existing species by a process called natural selection. ... Organisms that inherit that favorable new gene are likely to become more abundant than others of the species. Sometimes the population of a species becomes separated into two areas, by geography or by climate.
